Who might these "main proponents" be?

My only problem with alvarezsaurids is that I'm still not convinced that
_Mononykus_ and such are closely related to _Alvarezsaurus_, to the point of
being in the same family. There may have been a lot of convergence going on
that hasn't been accounted for. Maybe all that's required is a closer reread
of the relevant papers. Other than that, both _M_ (and _Shuvuuia_) and _A_ are
so clearly secondarily flightless that it's no longer worth commenting on.
